Mayweather vs. Berto Winner: Judges' Scorecards, Purse Payout and More

Floyd Mayweather Jr. is a master at dictating the flow of fights, and he did just that Saturday night while defending his welterweight world title belt in what appeared to be a triumphant bow on his historic career. 

With flurries of jabs and crazy-quick footwork at his disposal, Mayweather defeated Andre Berto (30-4) by unanimous decision, 120-108, 118-110, 117-111, to improve to 49-0 and tie Rocky Marciano's revered record.

Bleacher Report confirmed the result with a post on Twitter: 

"You have to know when to hang it up," Mayweather said, per ESPN.com's Brian Campbell. "It's my time to hang it up. ... Nothing else for me to prove in the sport of boxing."

If it was the final fight of Mayweather's career, he left with a hefty chunk of change to line his bank account with.  

According to ESPN.com's Dan Rafael, the Nevada Athletic Commission revealed earlier in the week that Mayweather was set to earn no less than $32 million for Saturday's fight. Berto, meanwhile, cashed out at $4 million—the biggest purse of his career. 

"I've accomplished everything, there's nothing else to accomplish," Mayweather said after the win, according to the Guardian's Bryan Armen Graham. "Money don't make me, I make money."

However, some argued that what Mayweather accomplished Saturday night wasn't exactly prolific. 

Campbell offered his take on the mismatch as the fight reached its anticlimactic conclusion:  

Sports Illustrated's Chris Mannix provided another telling ringside anecdote that summed up the cakewalk win:

They had a point. 

According to Showtime Stats on Twitter, Mayweather landed 56 percent of his total punches, while Berto connected on just 16 percent. 

So after starting his career a perfect 27-0, Berto has now dropped four of his last seven fights—three of which have come by unanimous decision.

But if there's a silver lining for Saturday's loser, it's that he landed two more punches (83) than Manny Pacquiao did in his unanimous-decision loss to Mayweather back in May, per ESPN Stats & Info.  

Mayweather stuck to his guns and employed familiar tactics throughout the early rounds, and his fleet-footed style allowed him to control the tempo and set the tone. 

That trend held steady, with Showtime Stats on Twitter noting that Mayweather landed 48 percent of his punches through four rounds, while Berto converted a paltry 13 percent. 

The seventh round proved to be the most action-packed of the night, as Berto finally flashed some of the power that originally put him on the boxing map. 

However, even a late flurry that momentarily stunned Mayweather couldn't swing the numbers in his favor, according to ESPN Stats & Info: 

Those lopsided figures summed up the evening.

Mayweather used his agility as a foundation to consistently evade Berto, and the hit-or-miss power-puncher couldn't match the sheer quantity of jabs Mayweather threw his way.

With one final vintage performance in the books that showcased his flawless technique, Mayweather should be content to leave the sport in younger hands as he heads for retirement without a loss to his name.
